I am developing a React native app. I am uploading a batch of images using react-native-image-crop-picker. Using the way that storing the path in an array and one by one uploading the image. but I can't produce the downloadable link for the uploaded files. I am getting 2 errors
1)Can not read property 'then' of undefined
2)when trying to get the downloadable link it cannot find the object
below is my code
AddProduct = () => {

I figured out it is not possible to share video content onto Instagram directly on Android in behalf of the user. This was my original intention.
Seems I can not use navigator.share call which works on iOS but not on Android, or only for text and url, but not for video / mp4.
I would not use MediaStore and similar React Nativ solutions as my app is a regular React.
What elso approach do you know?
I have now this:
const showShareDialog = async () => {
try {
log(
{
text: 'setIsDownloadFileInProgress(true) ' + getTempUserShortId(),
},
env
)
setIsDownloadFileInProgress(true)
const res = await axios.get(
`https://t44-post-cover.s3.eu-central-1.amazonaws.com/${imgId}.mp4`,
{ withCredentials: false, responseType: 'blob' }
)
setIsDownloadFileInProgress(false)
const shareData = {
files: [
new File([res.data], `${imgId}.mp4`, {
type: 'video/mp4',
}),
],
title: 'Megosztom',
text: 'Mentsd le a képekbe, és oszd meg storyban.',
}
//showShareDialog(shareData, 0)
if (navigator.share && !isDesktop) {
log(
{
text:
`navigator.share && !isDesktop shareData.files[0].size: ${shareData.files[0].size} ` +
getTempUserShortId(),
},
env
)
if (isAndroid()) {
const { status } = await MediaLibrary.requestPermissionsAsync()
if (status === 'granted') {
const asset = await MediaLibrary.createAssetAsync(res.data)
await MediaLibrary.createAlbumAsync(`${imgId}.mp4`, asset, false)
}
} else {
navigator
.share(shareData)
.then(() => {
log(
{
text: `'The share was successful 1 ` + getTempUserShortId(),
},
env
)
})
.catch((error) => {
log(
{
text:
`There was an error sharing 1 ${error} ` +
getTempUserShortId(),
},
env
)
})
}
} else {
log(
{
text: 'else ' + getTempUserShortId(),
},
env
)
setIsDesktopDownloadDialogVisible(true)
}
} catch (error) {
console.error(error)
log(
{
text: `a onclick error 2: ${error} ` + getTempUserShortId(),
},
env
)
}
}
i want pagination in my react native application so below is my code
<ListView bounces={false}
enableEmptySections={ true }
automaticallyAdjustContentInsets={ false }
dataSource={this.state.dataSourceRadio}
renderRow={(rowData, sectionID, rowID) => this.renderSiteView(rowData, rowID)}
onEndReached={this.onEndReached}
/>
onEndReached() {
if (!this.state.waiting) {
this.state.offset=10,
this.APIGetSiteGPS(this.state.token);
}
}
When i run above code next page data not come so any idea how can i solve this? your all suggestion are appreciable
I update my view in this method
_bindingRadioButtonData(data) {
this.setState({
dataSourceRadio: this.state.dataSourceRadio.cloneWithRows(data),
})
}
API call methods
APIGetSiteGPS(token) {
console.log(TAG + "customer Api: " + APPCONSTANTS.BASE_URL + "site" + " " + token)
fetch(APPCONSTANTS.BASE_URL + "site?&offset=" + this.state.offset, {

headers: {
'Accept': APPCONSTANTS.HEADERS.VALUE.ACCEPT,
'Content-Type': APPCONSTANTS.HEADERS.VALUE.CONTENT_TYPE,
'Authorization': 'Bearer ' + token,
},
})
.then(response => {
const statusCode = response.status;
const data = response.json();
// data: offset === 0 ? res.results : [...this.state.siteList, ...res.results];
return Promise.all([statusCode, data]);
})
.then((res, data) => {
this.responseReceive(res)
})
.catch((error) => {
this.stopLoadingIndicator()
console.log('error..', error);

temp.push(response[1].data.sites[i]);
}
this.setState({ siteList: temp})
setTimeout(() => {this._bindingRadioButtonData(this.state.siteList)}, 1000)

I developed a mobile app to help sharing things. The user has to give infos about what he is sending and he can add a picture of the object. So i used the cordova file, camera and fileTransfert plugins. It worked fine on most of the devices i tested on, but i discovered that in some other phone, it doesn't. While doing some tests and research on one of those phones, i discovered that the upload() method of FileTransfert i use to send images to online server seems like not able to reach the folder where the image is stored. Here is a sample of my code. Would you please help me to confirm if i am rigth and how to make those phones to be able to post pictures on the platform?

Sorry i found what the issue was and i fogot to put it here. The problem was actually about filesize. Filetransfert default limit is 7.5Mo. Sending file greater than that would fail. In some phones, camera default configurations put the picture size to 8 or greater Mpx. So that why it could not work in those phones.
I have tried several times to send the data and receive a response, but it does not seem to be sending the data put in by the user. I have tried going about this in several ways,I will share the code for the last two.
ONE
state = {
phoneNo: '',
pin: '',
isLoggingIn: false,
message: ''
}
_userLogin = () => {
console.log("userLogin");
this.setState({isLoggingIn: true, message:''});
var params = {
phoneNo: this.state.phoneNo,
pin: this.state.pin
};
var proceed = false;
fetch("https://"+"<url>", {
method: "POST",
headers: {
'Accept': 'application/json',
'Content-Type': 'application/json'
},
body: JSON.stringify(params)
})
.then(
(response) => response.json())
.then((response) => {
if (response.status == 200) {
proceed = true;
}
else {
this.setState({ message: response.message });
console.log(message); }
})
.then(() => {
this.setState({ isLoggingIn: false })
if (proceed) this.props.onLoginPress();
})
.catch(err => {
console.log(err.message);
this.setState({ message: err.message });
this.setState({ isLoggingIn: false })
});
}
Two
The only difference here is how I am handling the response so I will only add that section. I thought that the issue might be due to syntax at this point.
.then(function(response){
return response.json();
})
.then(function(data){
console.log(data)
I have been through various tutorials, github and stackoverflow pages addressing the issue but I seem to be missing something. I keep getting a JSON parse error and I am convinced that perhaps the data is never being sent to the url because I get the error regardless of user input.
Both input fields have a ref and the button points to the user login function.
<TextInput
ref = {component => this._pin = component}
placeholder="pin"
onChangeText = {(pin) => this.setState({pin})}
secureTextEntry = {true}
onSubmitEditing={this._userLogin}
/>
<TouchableOpacity
onPress={this._userLogin}
title = "Submit"
disabled={this.state.isLoggingIn||!this.state.phoneNo||!this.state.pin}>
<Text style={styles.loginText}>Sign In</Text>
</TouchableOpacity>
try something like this.
I also get problem acceding both status code & data from fetch call, so i made "processResponse" function
processResponse=(response) =>{
const statusCode = response.status;
const data = response.json();
return Promise.all([statusCode, data]).then(res => {
return ({
statusCode: res[0], // the status code
data: res[1] // the data of the GET/POST returned by fetch call
})
}
);
}
_userLogin = () => {
console.log("userLogin");
this.setState({isLoggingIn: true, message:''});
var params = {
phoneNo: this.state.phoneNo,
pin: this.state.pin
};
fetch("https://"+"<url>", {
method: "POST",
headers: {
'Accept': 'application/json',
'Content-Type': 'application/json'
},
body: JSON.stringify(params)
})
/*processResponse return both status and data , because when you make
.then((response) => response.json()) you return only data and status is removed
*/
.then(this.processResponse)
.then(res => {
console.log("response of fetch",res);
const { statusCode, data } = res;
if (statusCode > 200) {
this.props.onLoginPress()
}else{
this.setState({ message: data.message });
console.log("data message" , data.message);
}
this.setState({ isLoggingIn: false })
})
.catch(err=> {
console.error(err);
this.setState({ message: err.message});
this.setState({isLoggingIn: false})
});
});
}
AlainIb was very helpful and this helped contribute to what worked in the end. Using form data seemed to assist with the JSON Parse error. Hope this helps anyone else who is having any troubles.
state = {
message: ''
}
_processResponse = (response) =>{
const statusCode = response.status;
console.log("resp", response);
const data = response.json();
console.log("data", data);
return Promise.all([statusCode, data]).then(res => {
return ({
statusCode: res[0], // the status code
data: res[1] // the data of the GET/POST returned by fetch call
})
});
}
_userLogin = () => {
console.log("userLogin");
this.setState({isLoggingIn: true, message:''});
var params = {
phoneno: this.state.phoneno,
pin: this.state.pin
};
var formData = new FormData();
formData.append("phoneno", this.state.phoneno);
formData.append("pin", this.state.pin);
console.log(formData);
let data = {
method: 'POST',
headers: {
'Accept': 'application/json',
'Content-Type':'multipart/form-data'
},
body: formData
}
console.log(data);
fetch("https://"+"url", data)
.then(this._processResponse)
.then(res => {
console.log("response of fetch",res);
const { statusCode, data } = res;
if (statusCode == 200) {
console.log("in if statement");
if(data.login_success== 1){
console.log("name to be passed", data.name);
console.log("log in to profile");
this.props.navigation.navigate('ProfileRoute');
}else {
console.log("fail");
this.setState({message:"Password or Phone Number is Wrong"});
}
}else{
this.setState({ message: data.message });
console.log("data message" , data.message);
}
this.setState({ isLoggingIn: false })
})
.catch(err=> {
console.error(err);
this.setState({ message: err.message});
this.setState({isLoggingIn: false})
});
}
I'm using fetch for requests, and I want to submit a file along with other data. How can I do so?
If it is not possible using fetch, what should I do then?
Thanks you guys.
